17 Claims.

This invention relates to printing mechanisms adapted to print characters such as numerals, alphabetical characters, etc., upon a record sheet.

The main object of the present invention is to devise a printing mechanism which is especially adapted for performing printing operations at high speeds. In carrying out this main object of' the invention printing type are carried by a wheel which is rotatable and is in continuous rotation. When the preselected type is at the printing line anA impressionis taken from the type Without interrupting the rotation of the wheel or the driver that elects its rotation.

Anoher object of the present invention is to devise a printing mechanism for printing alphabetical characters and numerals utilizing a conventional platen and avoiding the use of type hammers. The use of a conventional platen is of great importance and advantage since it permits a more satisfactory means for carrying a sheet to be printed and for feeding the sheet in line space or variable spacing operations.

Another object of the present invention is to provide an improved arrangement for taking an impression from a selected type onto the platen without stopping the rotation of the wheel carrying the type but, nevertheless, ytaking the impression when the type is stationary. This apparent inconsistency is effected by causing the printing Wheel to be rotated in one direction and then causing the printing wheel to roll over its operating gear in the opposite direction as the printing wheel is rocked toward the platen so that the selected type is stationary when it strikes the platen. By this arrangement the printing wheels operate as type hammers and impressions are eiected while type are stationary lwithout interrupting the rotation of the printing wheel or its driver, and the use of. a conventional platen is permitted. l

Another object of the present invention is to arrange the type elements in the printing wheel in groups, therein being one group of numeral type and three'groups of alphabetical characters, and to provide means under control of a selecting means to select the desired group of type and select the desired type of the selected group.

This is attained by analyzing .a perforated card to selecta type in the four different groups and then selecting the desired group by the analyzing oi special holes in the same card.

Another object of the present invention is to cause group and type selection to be effected in the 'same analyzing cycle of the same card.

The numeral type 1-9 are selected by perforations 1-9 and at a desired point in the operating cycle an impression is effected from the selected type. Alphabetical characters are selected by (Cl. lol- 93) effecting an impression at points in the cycle earlier than the printing impression is effected from the numeral type, and the points in the cycle are selected under control of the special holes. This arrangement is also a broad object of the present invention as it provides a numeral and alphabetical type printing mechanism operating for printing impressions in different points in the cycle. This division results in a smoother operating cycle since hammer blows are eiected at four different points in the cycle instead of a single point. The shocks to the machine eected by the hammer blows are thereby distributed and are less in intensity so that the parts to which shocks and strains are distributed can be less rugged in size thus cheapem'ng the cost of manufacture and diminishing the service requirements.

Further objects of the instant invention reside in any novel feature of construction or operation or novel combination of parts present in the embodiment of the invention described andl shown whether within or without -the scope of the appended claims and irrespective of otherspecic statements as to the scope of the invention contained herein.

The machine in which the present improvements have been incorporated is well known and is exemplified in the patents to Lake No. 1,379,268, dated May 24, 1921, Lake No. 1,600,413, dated September 21, 1926, and the patent to Daly et al. No. 1,896,540, dated February 7, 1933.

In machines illustrated in detail in the above described patents and generally henein, tabulating cards I0 (Fig. 2) are adapted to be fed singly or by a picker Il from a supply stack to a pair of upper feeding rollers I2 which convey the card so as to have the perforations of the card analyzed by the usual perforation analyzing brushes I3, while the card is in motion. The card analyzed then passes to a lower set of feedin the accompanying drawings ing rollers I4 which'then convey the card to a `stonage hopper, usual in the type of machine referred to.

Card feeding operations are instituted by the usual manual start key designated asv ST in the last mentioned patent so as to cause by an electrical circuit the energization of a card feed clutch magnet I5.

The power for driving the card feeding rollers and other parts of the machine is derived from a motor (not shown) which by a belt I6 and pulley I1 constantly rotates a ratchet wheel I9 secured thereto. The pulley I1 and ratchet wheel I9 are loosely mounted upon a shaft I8.

In Fig. 2 there is shown the card feed clutch for causing card feed and is similar to the card feed clutch disclosed in Fig. 1d. of the Lake Patent No. 1,822,594, dated September 8, 1931, to which reference should be had for details of construction and operation.

Upon completion of the electrical circuit to clutch magnet I5, the latter attracts its armature to raise a clutch lever 2l to thereby unlatch the latter from a clutch pawl 22. The latteris then drawn by a related spring 23' to engage the constantly rotating ratchet wheel I9. The clutch pawl 22 is carried by a bar 25, which is secured to a disk 26 secured 'to shaft I8 and to the latter there is secured a pinion 21.

'I'he construction and operation of the cardk feed clutch, as is well known, are such that upon energization of magnet I5, disk 26 will be rotated and successive rotations of the shaft I8, and therefore pinion 21, will ensue as long as tabulating operations are desired.

The pinion 21 is in mesh with a gear 28 and the latter drives the upper set of feeding rollers I2 and the lower set of feeding rollers I 4. The upper set of feeding rollers is intergeared by pinions 29,

Q one of which is rotatable with a gear 30 in mesh with the driving gear 28. 'Ihe latter also meshes with a pinion 3| which is rotatable with one of a pair of intergeared pinions 32 carried by the rollers,l4 which drive5the lower set of feeding rollers I 4 in opposite directions. The driving gear 28 is of suicient width to drive a gear 34 so that by a train of gears 35, 38 a shaft 31 is driven. It is understood that as is usual in tabulating machines the card feed clutch is so designed and thegears are so proportioned that shaft 31 will be given a complete revolution in the arrow direction shown in Fig. 2.

Itis customary in the type of machine described to cause printing from numeral type of a printing mechanism which are presented to a printing line and which are selected in accordance with the analyzing of the perforations of the card, and to carry out the printing function in a novel manner an improved construction will now be described.

Numeral printing mechanism As best shown in Fig. 4, to the shaft 31 which rotates one revolution for each card cycle there is secured a gear 38 which through a speed reduction mechanism, to be hereinafter described, drives a pinion 39 attached to a clutch-shaft 40, the driving connection being such that shaft 40 will be driven two revolutions for each revolution of shaft 31.

Shaft 40 xedly carries a notched clutch disk 4I (Fig. 1) and adjacent the clutch disk M there y is loosely mounted gear 42 to which is pivotally mounted a spring urged clutch pawl 33, the latter being normally engaged by a clutch release arm 44 so as to hold the clutch tooth 45 out of engagement with a clutch notch of the clutch disk 4I.

'I'he above described clutch is the printing type selecting clutch and causes the differential rotation of a printing wheel 48. To rotate the type wheel 48, the gear 42 meshes with an idler gear 48 loosely mounted on a shaft 41 and the gear '48 meshes with the type carrying wheel or gear 48- carrying the digit printing type 0-9 inclusive and comprising the numeral type group, the numeral type being spaced four teeth apart.

Fig. 1 shows the arrangement fof the printing devices for a single order and the machine is pre1'- erably provided with duplicate devices for printing the digits of different denominational orders.

The card is perforated with holes to represent the digits 0-9 and is passed by the analyzing brushes I3 to analyze the index points in the order When the analyzing brush I3 senses a hole, a

circuit is closed to a printing control magnet 49 (Fig. 2) and for each card column analyzed, there is a printing control magnet 49. When a printing control magnet 49 is energized, its armature 50 (Fig. 1) is attracted so as to pull a' call'wire 5I l to the right. 'I'he latter has a head portion comprising extensions 52 and 53, the extension 52 normally engaging a lug of an arm 54 -which is the integral depending part of the clutch release arm 44. The normal engagement of extension 52 and lug 53 is retained during the time the holes 9, 8, 7, 6, 5, 4, 3, 2, and 1 are analyzed to thereby cause the clutch release arm 44 to be rocked. The clutch pawl-43 is now rocked by its spring to cause its tooth to engage a particular notch of the clutch disk 4I to thereby cause the gear 42 to be rotated land through the idler gear 48 rotate the printing gear wheel 48.

If the "9 or rst hole was analyzed, the clutch disk 4I would rotate the extent of one notch before the clutch engagement is effected by the energization of the magnet 49. 'I'he printing wheel 48 will thereafter rotate so as to bring the "9 numeral type to the printing line.

In the above manner the printing type wheels are picked up at differential times so that at a predetermined point in the cycle of machine operation the printing wheels will represent at the printing line the selected digits, it being noted that the 0 type is normally at the printing line so that no movement of a printing wheel is necessary to select "0 for printing.

From Figs. 1 and 3, it will be'seen that the free ends of the call wires 5I pass between a rod 55 and a bar 56 of a bail shaped frame which is pivoted at 51. One side arm of the bail shaped frame has a depending followerarm 58 carrying a roller 59 coacting with a cam 60 secured to the shaft 31. v

After the 1 index point is analyzed, the 0 hole is sensed by the analyzing brush if it is present but before analyzing the "0 hole, an inclined cam edge 60a (Fig. 1) of a high portion of cam 60 acting on the follower arm 58 rocks the bail shaped frame clockwise causing the rod and bar 5G to depress all the free ends of the call wires 5I so as to disengage the extensions 52 from the lugs of arms 54. Obviously, with this relationship even though a magnet 49 is energized by the presence of a "0 hole, the printing type selecting clutch for rotating the printing wheel will not be engaged so that, when the printing impression is effected, the 0 digit will be printed.

Each printing wheel is carried by an arm 6| loosely pivoted on the shaft 41 and is provided with follower arms 62, each oi' which engages a related cam of a pair of complementary cams 63. Referring to Fig. 4, attached to the shaft 31 -is a gear 66 driving a pinion 66 attached to a shaft 8 61. There is a printing clutch for each printing wheel for causing the impression to be effected and is similar to the previously described printing type selecting clutch and comprises the clutch disk 64, a clutch pawl 68 carried by one of the complementary cams 63 and a clutch release arm 69 having an integral depending arm 18.

For each printing wheel that is set to any `digit from 1 to "9, a cam 1| attached to a related gear 46 will rock a double arm 12. One end of each arm 12 carries a pin 14 engaging a slot 15 of a link 16, the latter being pivoted at 11 to anl lnterposer 18, a series of the interposers 18 being pivoted on a rod 19. Obviously, when the double arm 12 is rocked by the cam 1|, the link 16 is depressed to rock the related interposer 18 to bring its free or right end in front of a lug 88 o the arm 18.

The interposers 18 are carried, as stated, by the rod 19 and the latter is carried by a pair of dea projection 82 coacting with a profile cam 83 secured to the shaft 31. y l

After all the index points of the card which comprises the index points -9 andthe special index points X and R have been analyzed, the projection 82 will drop from the high part of the cam 83 to a low part 83a permitting a spring 84 attached to an arm 8| to shift all the interposers 18 to the right and those that have been rocked by the depression of a related link 16 will by their shifting rock the arms so and, therefore, the clutch release arms 69, causing the 4clutch engagement so that complementary cams 63 will now rotate to rock all the arms 6| to force 'the printing wheels 48 against the usual inking ribbon and platen 86 around which is fed a paper to be imprinted.

As each arm 6| is rocked, the printing wheel is rotated counterclo se but, since the printing wheel is rolling over the gear 46, this rolling action will cause an equal and simultaneous rotation in a clockwise direction. Both of these opposite rotations will, in effect. cause the printing wheel 48 to be substantially stationary when it strikes the platen 86, the type strikingthe lattersquarely and rmly to cause a legible impression.

After the index points 9-1 have been analyzed, it is desirable to positively retract all`of the attracted armatures 68 in the event that residual magnetism causes them to remain attracted to the cores, so that they may again be attracted, preferably for a purpose to be later understood in connection with alphabet type selection.

Tothis end each call wire 6| has anextension 98 cooperating with a bail 8|, the latter being normally positioned so as to permit the call wire 6| to be freely shifted to the right when a magnet 49 is energized.

88 The bail shaped frame 9| is pivoted'at 92 and has a depending arm 93 .having an extension 94 cooperatingv with a cam 9,6. After analyzing the 1 index point, a high portion 96a of cam 96 engages the extension 94 and thus rocks bail 9| 7l to the left Ato retract all the call wires, if they have not been retracted. This operation occurs just slightly before the call wires 6| are depressed by the rod 66 and bar 66. y After the printing operation, since the clutch u is still engaged, the printing wheels continue to pending arms 8|, one of which is provided withY rotate until the clutch pawI 43 strikes the clutch release arm 44 thereby disengaging the clutch and which is effected when the printing wheels are at 0.

'I'he clutch which causes the rotation of the cams 63 to effect the imprint continues its engagement for a complete rotation of the cams 63 and the clutch disengagement is effected by the engagement of the clutch pawl 68 with the arm 69.

Zero insertion In printing a multi-denominational number as 3;00 it is necessary to insert the zeros to the right of 3. This is effected by the usual coupling levers 86, each of which is pivoted on the link 16 and has a lug 81 engaging a lug 88 of a pitman next lower in order so as to rock the interposer lower in order if the related printing wheel has not been set, to thus cause 0 printing.

By adjusting the coupling levers to disengage the lugs 81 and 88, the printing mechanism may be split at desired points, as is well known in the art.

Alphabet printing mechanism The machine is preferably provided with alphabet character printing type and means for selecting such type so as to print, asidefrom numerals, letters making up words or abbreviations.

The alphabet type are selected according to groups, the code being shown in Fig. 1a. The particular group selected determines which of the several type related to an index point will be printed. For example, if the perforation should be the 2 hole, and no pilot hole is utilized in either the O, X or R positions 2 `will be printed. If ahole is also at O, the Of hole will select the type S. If at the X index point position type K will be selected, and if at the R index point position type B will be selected.

To more clearly understand the principle of operation, it should be noted-that from the timing diagram of cam 83 the selected numeral type have their impressions taken therefrom after all the index points have been analyzed and, of

course, is after the R index point has been analyzed. The alphabet type selection is provided for by taking the printing impression before the time a numeral type would have been printed and this is effected under controlI of the ingimpression clutch 64-68 was engaged, the

printing wheel 48 will be rocked earlier than for printing a numeral 9 to take an imprint from the "I type. The perforation at the X position will take an imprint still earlier to print R and the perforation at the O position still earlier than to print "R to print Z.

The same principle of operation is provided for selecting the other alphabet type.

It will be recalled that, after the "1 perforation is analyzed, bail 9| positively retracts the attracted armatures 68 and thereafter members 66 and 66 are depressed so as to cause the call wires 6| to be disengaged from the arms 64 and to cause the extensions 63 of the call wires to be placed in front of the lugs 88 of the arms 18..

Obviously, the energizationof a magnet 49 will,

after the "1 perforation is analyzed, cause the arm 10 to be rocked and the clutch release arm 69 to.be rocked, and at a time depending upon the pilot hole analyzed. Hence, the type printing clutch 64-68 will be released to cause the printing'impression from the selected type.

It is pointed out that for alphabet type printing, impressions are vmade at three different points in the operation cycle or after the O, X and R perforations are analyzed, whereas for numeral printing the impressions are made only after all the perforations are analyzed and .at a single point in the operating cycle.

Attention is directed to Fig. 4 which discloses a speed reduction mechanism for shaft 40, the

shaft 61 being rotated at a constant speed by the gear driven by shaft 31.

This speed reduction mechanism comprises an arm 96 pivoted by a stud 91 on the gear 65 and thereby said arm 96 is givenv a clockwise rotation of one revolution for each card cycle. -The arm 96 carries a roller 98 engaging the cam race of a box cam 99 (Fig. 3) fixed to a side frame by screws |00. The gear 88 is loosely mounted on the shaft 31 and carries a stud |0I forming the pivotal point of a block |02 engaged by forked extensions I03 of arm 96.

The arm 96 is varied in its angular position with respectto the gear '65 by the configuration of the cam race of the box cam 99 so that in the clockwise rotation of the gear 65 the arm 96 is rocked so that its free end is moved towards the shaft 31, thus causing the gear 38 to back up with relation to thegear 65 thus causing the gear 38 to fall behind the gear 65 and reducing its speed.

The cam race portion |04 of the box cam has a configuration which effects'a driving of the gear 38 at the same speed as the gear 65 so that during the analyzing of the index points 9-2, the gears 65 and 38 rotate at the same speed, each gear rotating 18 per` index point, or a distance l equivalent to four teeth of the type wheel. Thereafter at labout the cam portion E05 the arm 96 is rocked towards the shaft 31 rocking the 'gear 88 backwardly with respect to the gear 65, thus reducing the speed of the gear y36. Thereafter, the cam portion |86 rocks the arm 96 still furthertowards shaft 31 but in such a manner as to render the speed of gear 38 constant 'and equal to one quarter of the speed of gear 55, during which time the selected numeral or` alphabet type are printed from. The nal cam portion |01 increases the speed of gear 38 so that during the final part of the cycle, the gear 38 is finally restored to the normal relation witherespect to gear 65.

The purpose of the speed reduction which causes vby the ca m portion |03 the gear 38 to rotate one quarter the speed of gear 65 is to select for printing a particular type within the group of type related to the same index point. The printing operation for alphabet type is effected by the engagement of clutch 64;-68 when the index points O, X and R are analyzed, these index points having the same spacing. as the index points 9-1. However, to keep the printing wheel 48 small in diameter, the alphabet type are arranged closely so that to select these type -the printing wheel must rotate at a reduced speed as the index points "0, X and R are analyzed.

For a more concrete illustration take, for example, the selection for printing of the alphabet type X selected by the two holes 7 and O. When the 7 hole is sensed, the printing wheel starts to turn at about 54 and, if it should rotate at a constant speed, the printing wheel would have rotated 30 teeth at the time O hole was analyzed to cause the printing and at this time the printing wheel would have been in such a position to print` Q instead of X. If the pilot hole was the X hole, an R would be printed instead of P and, if the pilot hole was the R" hole, a blank would be printed instead of G. Without the speed reduction at the numerical printing time for printing '1 the clutch 4|-45 would have been latched up so that a O would be printed. Therefore, such constant speed cannot be named and the speed reducing mechanismphabet type are substantially stationary when an impression is eiected therefrom.

While there has been shown and described and pointed out the fundamental novel features of the invention as applied to a single'modication, it will be understood that various omissions and substitutions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention.
